SPECIFICATION forming part of Letters Patent No. 338,052, dated March16. 1886.

Application filed August 31, 1885. Serial No. 175,599. No model.)

To all whom, it may concern.-

Beit known that I, HIRAM G. FARR, of Boston, inthe county vof Suffolkand State of Massachusetts, have invented certain Improvements inLubricating Axles for Vehicles, of which the following is a fullfclear,and exact description, reference being had to the accompany] ngdrawings, making part of this specication, in which- Figure 1 is a planof the upper side of the journal of an axle constructed in accordancewith my invention. Fig. 2 is a longitudinal section through the center`of the same; Fig. 3, a similar section with the axle box in place uponthe axle. Fig. 4 is a view of the same. Fig. 5 is a transverse sectionon the line x x of Fig. 3. Fig. 6 represents one form of wick forfeeding the lubricant to the outside of the axle-journal; Fig. 7,another form of wick for feeding the lubricant. Fig. 8 represents anaxle having a single collar, instead of two, as shown in Figs. 1, 2, 3,and 4; Fig. 9, a transverse section through a collar.

In the said drawings, A represents the j ournal of a non-revolving axle,having a longitudinal channel, a, cut in its upper side, for thereceptionof a lubricant and a strip of felt or other suitable material,which serves as a wick, b, for feeding the lubricant upward. The ends ofthe channel are slightly rounded, as shown in Figs. 2 and 3, and thelength and shape of the wick may exactly or nearly correspond with thatof the channel a, Fig. 6, or may have its under side corrugated, Fig. 7,the straight edge of the wick being uppermost when located within thechannel. Surrounding the inner end of the journal are two collars, c c,Figs. l, 2, and 3, with a short space intervening between them. In eachcollar (which is formed in the upper side of the journal) `is cut anotch, d, the form of the outer notch being rectangular, as shown inFigs. 2, 3, and 9, and the notch in the inner collar wedge shape. (SeeFigs. 2and 3.) Within these notches d al is located a continuous stripof felt or other fibrous material, which is saturated with the lubricantand serves as a wick, e, to lay it upon the inner surface of theenlarged portion of the axle-box B, which surrounds the collars.

over the outer screw-threaded end of the axle.

h is a suitable washer interposed between the outer collar, c, of thejournal and the contiguous annular shoulder of the axle-box B,to preventundue lateral play. The wick e, besides lubricating the interior of theenlarged portion of the axle-box, also performs the office of adust-arrester, should any be able to penetrate at the annular line ofthe joint between it and the journal.

Vhen the lubricant and wicks are once applied to the axle, no attentionneed be given for several months thereto, and a carriage provided withmy aforesaid axles can run with perfect ease and freedom from liabilityof the heating and setting of its wheels incident to axles of theordinary construction.

The aim of this invention is to reduce to a minimum the friction betweenthe journal of an axle and the box or bearing of a wheel revolvingthereon; and my present invention consists in a non-revolvingvehicleaxle having at the inner end of its journal one or more collars,each provided with a notchin its upper side for the reception of a wicksaturated with alubricant, the journal also having a longitudinalchannel formed in its upper side, for the reception of a lubricant and awick,which feeds it by capillary attraction in proper quantities to theinterior of the wheel box or hub revolving thereon,by whichconstruction,after being once oiled, the axle needs no renewal of thelubricant for a considerable period of time.

W'here the journal has but one collar, c, Fig. 8, I prefer to have thenotch d wedge shapee., have its bottom taper upward and inward--for thepurpose of preventing the wick e from being forced out of its position.

I claiml. A non-revolvingjournal, A, having one or more annular flangesor collars, c, each provided with a notch, d, for the reception of alubricated wick, e, and with a longitudinal channel, a, for thereception of a lubricant and IOC Wick, b, a threaded outer` end, and anut, C, Witness 4my hand this 27th day of August, turned thereover, incombination With a re- 1885.
